Dachstein Krippenstein — The 5 Fingers & Alpine Shark

High above the UNESCO World Heritage village of Hallstatt, the Krippenstein plateau is a vast, karst landscape that feels like another planet. The trail leads from the cable car mountain station to the '5 Fingers'—a viewing platform shaped like a hand reaching out over a 400m drop toward Lake Hallstatt. Further along the Heilbronn Circular Path, hikers encounter the 'Dachstein Shark', a massive metal sculpture that reminds visitors that this 2,100m high limestone plateau was once the bottom of the ocean.

Reinebringen is undoubtedly the highly recognizable and photographed viewpoint in the Lofoten Islands, and perhaps all of Norway. This short, aggressive 1.2-mile (2km) round-trip hike skyrockets out of the ocean to an altitude of 448m. The trail was famously dangerous and eroded due to massive over-tourism, so a team of Nepalese Sherpas was hired to build a massive, 1,978-step stone staircase up the mountain. Conquering the stairs leads to a dizzying, knife-edge ridge that drops vertically into the ocean, offering a mind-blowing bird's-eye view directly down onto the picturesque fishing villages of Reine, Sakrisøy, and Hamnøy, connected by bridges across the deep blue fjords.
